Hi Dr Sher, I have a blastocyst with a partial deletion of the X chromosome (there are 46 chromosomes in total). The embryologist said they do not know if it would lead to a normal healthy baby as it is only a minor error. Do you think this embryo is viable? If it did lead to a live pregnancy what might the issue be with the baby?
I would be worried because there have been reports of Turner Syndrome with partial deletion of the X chromosome long arm.

Hi Dr Sher, speaking to my embryologist I understand that euploid blastocysts could become aneuploid over time once implanted. If that is the case, is it possible for aneuploid embryos (not mosaic) to correct and become euploid? Thanks so much in advance!
No it is not possible for aneuploid embryos derived from aneuploid eggs to autocorrect.

Hello. I have a question that has stumped even my RE! I just had my third (ugh) failed cycle. Only 5 eggs retrieved and all 5 were immature. I’m 36, borderline dor, (fsh between 9-12, amh 2) + MFI. This cycle was antagonist and my estrogen reached only about 2300. Though I don’t get a lot of eggs and have had an issue with getting mature eggs, I was able to get some mature eggs during cycles 1 and 2 (though not many) with estrogen numbers about the same as this last cycle. First cycle was also antagonist and second was estrogen priming w/ microdose lupron. Any thoughts on what protocol I should be trying next to get more mature eggs?
Hi Beth,
In my opinion, ther MOST likely factor is the protocol used for ovarian stimulation. I would drastically modify what you have been on.
In my opinion, the protocol used for ovarian stimulation, against the backdrop of age, and ovarian reserve are the drivers of egg quality and egg quality is the most important factor affecting embryo “competency”.
Women who (regardless of age) have DOR have a reduced potential for IVF success. Much of this is due to the fact that such women tend to have increased production of LH biological activity which can result in excessive LH-induced ovarian male hormone (predominantly testosterone) production which in turn can have a deleterious effect on egg/embryo “competency”.
While it is presently not possible by any means, to reverse the effect of DOR, certain ovarian stimulation regimes, by promoting excessive LH production (e.g. short agonist/Lupron- “flare” protocols, clomiphene and Letrozole), can in my opinion, make matters worse. Similarly, the amount/dosage of certain fertility drugs that contain LH/hCG (e.g. Menopur) can have a negative effect on the development of the eggs of older women and those who have DOR and should be limited. I try to avoid using such protocols/regimes (especially) in women with DOR, favoring instead the use of the agonist/antagonist conversion protocol (A/ACP), a modified, long pituitary down-regulation regime, augmented by adding supplementary human growth hormone (HGH). I further recommend that such women be offered access to embryo banking of PGS (next generation gene sequencing/NGS)-selected normal blastocysts, the subsequent selective transfer of which by allowing them to capitalize on whatever residual ovarian reserve and egg quality might still exist and thereby “make hay while the sun still shines” could significantly enhance the opportunity to achieve a viable pregnancy

If you have two CGH normal embryos but one was day 5 and one was day 6, is the day 5 preferable? Do day 6 normal embryos implant at lower rates than day 5?
In my opinion, they both should do equally well!

Hello dear Dr.Geoffrey, I am about to start my treatment for IVF, my doctor put me on Progynova 2mg 4 tablets a day for 10 days to start, I have PCOS and Endometriosis, please if you could advise me on it, is it a good decision? I am worried about the high level of estrogen contained in the tablet not to worsen my condition thank you
Hi Lina,
AS I repeatedly have stated , IVF is not strictly a science. Rather it is an art science blend. Approaches to stimulation do differ widely. Thus while I personally do NOT use estrogen priming on women with high or normal ovarian reserve (e.g. PCOS), some might do so. In my opinion, there is little benefit in doing so and again, in my opinion, further bolstering of the estrogen level might not good for the eggs in such cases.
